/* ui-kit.css — layout tokens + Game-Day Kinetic utility classes
 * shared across every authenticated portal AND public marketing
 * surface.
 *
 * @sportfed/theme/tokens.css owns *visual* tokens (color, type,
 * radius, motion). This file owns *layout tokens* + *utility classes*
 * that are reusable across surfaces.
 *
 * Two roles, one file:
 *   1. Layout tokens (--sf-page-*, --sf-side-nav-*, …) — uniform
 *      across portals regardless of palette.
 *   2. Utility classes (.sf-btn, .sf-pill, .sf-eyebrow, .sf-card,
 *      .sf-display-italic, .sf-3d-placeholder, .sf-marquee, …) —
 *      ported from design/system/claude-design/. These are reusable
 *      enough that componentizing each into a Lit element would be
 *      over-engineering; they sit cleanly as classes on plain HTML.
 *      Lit primitives that NEED encapsulation (sf-service-mark,
 *      sf-ticker, sf-3d-placeholder) live in src/* and may consume
 *      these classes from the host document.
 *
 * Every host portal MUST include this stylesheet at the document
 * level so the variables resolve and the utility classes are
 * available to slotted content.
